Ginathum leve, Bailey. 1 propose this name for a small miero- 
scopic plant which I have found growing in considerable abund- 
ance as a parasite on stems of Nitella. The whole Alga consists 
of a single irregular branching layer of green cells, which like 
those of Coleochete scutata are closely adherent to ‘the plant on 
which it grows, but it has no trace of the setiform processes be- 
longing to that species. It appears to grow both by the —- 
of new cells and the spontaneous division of the-old o In 
many of the cells one or more small vesicles, pain tim >) simi 
lar to those in the spiral threads of Zygnem, were observed. 
No other traces of fruit have been seen. Its place in the systems 
must be near Coleochete. Autindint on stems of Nitella, in

Sulva , Harv. mss. I found this forming erect tufts 
in small pools of water between high and low-water mark, in 
cavities of the granite blocks, composing the pier at Stonington, 
C Whether its color has been affected by exposure to air 
and sunlight, I cannot say. Harvey says, “I do not know any 
thing like it.” 
Lyngh ya crispa? Ag. A plant which grows in immense quan- 
tities in salt water ditches, near Hoboken. It appears to me to 
be identical with English specimens aval L. ferruginea, Ag., 
which I received from J. Ralfs, Esq., but Harvey says, “it agrees 
better with some specimens of is crispa, Ag., res er which name, 
probably more than one species are confoun 
scillatoria F'riesii ? Ag. A common plant (et. erect tooth- 
like fasciles half an inch in height, among mosses on damp Xda 
near West Point. I sent it by the name of O. Friesii to arvey 
and he ‘orapeae concerning it, “this looks different from O. 
Friesii, but comes near it. It i is, probably, a different species. 
But in the fearful confusion that reigns here, I have no fancy 
making more names. 
Tetraspora lacunosa, Chauy. in Duly. Bot. Gall. I am. in- 
formed by Dr. Montagne that this is the. same as the plant which 
had named 7’. perforata, under the supposition that it was an 
undescribed species. 
emania Americana, Harv. mss. This species is founded on 
* Alga which grows in rivers in Virginia, and which I had sup- 
to be only a variety of L. fluviatilis, Ag. Harvey remarks 
that “the European plant is very much more simple with distant 
nediiee the American one is much branched ane a
